Contraception - barrier methods and spermicides

Last revised in July 2026

Barrier methods of contraception include:Male and female condoms.Diaphragms and caps.Spermicides.

Contraception - barrier methods and spermicides: Summary

  • Barrier methods of contraception include:
    • Male condoms.
    • Female condoms.
    • Diaphragms and caps.
  • Male and female condoms prevent pregnancy by providing a barrier to the ejaculate, pre-ejaculate secretions, and cervicovaginal secretions. This prevents fertilization and reduces the risk of sexually transmitted infections (STIs).
  • Diaphragms and caps fit into the vagina to cover the cervix, thus excluding semen. They must be used in conjunction with a spermicide.
  • If a person is considering using a barrier method of contraception:
    • An assessment should be done to confirm the suitability of the method. As part of the assessment, the World Health Organization Medical Eligibility Criteria for Contraceptive Use should be applied to assess the person's eligibility for use of the method.
    • Verbal and written information should be provided on how the barrier method works, as well as the efficacy, advantages, disadvantages, possible adverse effects, and how to use the method correctly.
    • Advice should be offered on other methods of contraception, such as long-acting reversible contraception (LARC), and their comparative efficacy.

Have I got the right topic?

From age 13 years to 60 years.

This CKS topic covers the use of barrier methods of contraception, including male condoms, female condoms, diaphragms, and cervical caps.

This CKS topic does not cover the use of other methods of contraception or the management of women requesting emergency contraception. It also does not cover factors affecting the choice of contraception, such as comorbidities, reproductive history, drug treatments, and age; ethical and legal issues around contraception; safe sex advice; or assessment for sexually transmitted infections.

There are separate CKS topics on Contraception - assessment, Contraception - emergency, Contraception - combined hormonal methods, Contraception - IUS/IUD, Contraception - natural family planning, Contraception - progestogen-only methods, and Contraception - sterilization.

The target audience for this CKS topic is healthcare professionals working within the NHS in the UK, and providing first contact or primary healthcare.

[NICE, 2021]

Background information

What types of barrier contraception are available?

  • Barrier methods of contraception include male condoms, female condoms, diaphragms, and cervical caps.
  • Male condoms are worn on the penis during sex. 
    • They are made from latex or non-latex (polyurethane or polyisoprene) materials and are available in a variety of sizes, styles, textures, colours, and flavours.
    • Different condom sizes are available in the UK. Optimal fitting may require trying a variety of condoms.
    • Condoms lubricated with spermicides are available but are not recommended. See the section on Spermicides below for more information. 
  • Female condoms are worn inside the vagina during sex. 
    • They are sometimes known as 'internal condoms'.
    • They consist of a loose-fitting polyurethane sheath pre-lubricated with dimethicone, an odourless, non-spermicidal lubricant.
    • The closed end of the condom has a polyurethane ring that is placed inside the vagina. The condom then lines the vagina, and the opening of the condom (which also has a polyurethane ring) lies just outside the vagina. 
  • Diaphragms fit inside the vagina and over the opening of the cervix.
    • They consist of a thin, soft dome with an encased flexible steel ring around its edge, and are designed to fit between the posterior fornix of the vagina and the pubic bone. They are held in place by the vaginal muscles, the tension of the ring, and the pubic bone.
    • Coil spring diaphragms have a soft, flexible rim. They are made from latex or silicone and are suitable for women with a normal pelvis and deep pelvic arch. The sizes range from 60–90 mm in increments of 5 mm. 
    • Arcing diaphragms have a firm rim and are easier to insert. They are silicone-based and are useful for women with poor vaginal muscular support and those in whom the length or position of the cervix makes fitting a coil spring diaphragm more difficult. The sizes range from 60–90 mm in increments of 5 mm. 
    • Caya® is a one-size diaphragm designed to fit most women (about 80%). It is silicone-based with a flexible rim and grip dimples to help with insertion, and a removal dome to help with the removal. It is available online and over-the-counter. The College of Sexual and Reproductive Healthcare (CoSRH) advises that Caya® will not be suitable for all women and some women may still require assistance from a health professional to ensure correct fitting prior to use [CoSRH, 2014].
  • Cervical caps are smaller than diaphragms.
    • They fit directly over the cervix and are held in place by suction and by support from the vaginal wall.
    • They are an alternative for women who do not want to (or cannot) use a diaphragm, and they may fit better than a diaphragm in women with poor muscle tone or prolapse.
    • FemCap® (available in the UK) comes in 22, 26, and 30 mm sizes.
  • Spermicides provide a chemical barrier to sperm and must be used with diaphragms and cervical caps. 
    • Most spermicides available in the UK contain nonoxinol-9 (N-9).
      • N-9 is a surfactant that disrupts cell membranes.
      • In human and animal models, epithelial disruption in the vagina and rectum has been identified with N-9 use.
      • Repeated and high-dose use of N-9 is associated with an increased risk of genital lesions, which may increase the risk of HIV acquisition/transmission.
    • There is no evidence that condoms lubricated with spermicide provide additional protection against pregnancy or sexually transmitted infections (STIs) compared with condoms lubricated with a non-spermicidal lubricant.
    • The use of condoms lubricated with N-9 is not recommended due to the increased risk of HIV acquisition/transmission.

[CoSRH, 2015; BNF, 2026]

How do barrier methods of contraception work?

  • Male and female condoms provide a barrier to the ejaculate, pre-ejaculate, and cervicovaginal secretions.
    • They can be used as a primary method of contraception or as an additional method either in the short term (for example, when starting hormonal contraception) or in the long term (to provide double protection).
    • They can also be used to reduce the risk of sexually transmitted infections (STIs) and HIV.
    • The use of condoms lubricated with spermicide is not recommended. See the section on Spermicide for more information.
  • Diaphragms and cervical caps provide a physical barrier to sperm reaching the cervix.
    • When inserted correctly, they fit into the vagina to cover the cervix, thus excluding semen.
    • As only the cervix is covered by these methods, they do not prevent exposure of the vaginal mucosa to semen or exposure of the penis to cervicovaginal secretions. 
    • Diaphragms and caps must be used in conjunction with a spermicide. The spermicide is held against the cervix by the diaphragm or cap and provides a chemical barrier to sperm.

[CoSRH, 2015]

How effective is barrier contraception at preventing unwanted pregnancy?

  • Male condom
    • When used perfectly (consistently and correctly), the male condom can be up to 98% effective at preventing pregnancy. This means that 2% of women will conceive within the first year of use due to method failure.
    • When used typically, 13% of women will conceive within the first year of use due to method failure or user failure.
    • Pregnancy rates are similar for latex and non-latex condoms.
  • Female condom
    • When used perfectly (consistently and correctly), the female condom can be up to 95% effective at preventing pregnancy. This means that 5% of women will conceive within the first year of use due to method failure.
    • When used typically, 21% of women will conceive within the first year of use due to method failure or user failure.
  • Diaphragm plus spermicide
    • When used perfectly (consistently and correctly), 17% of women will conceive within the first year of use due to method failure.
    • When used typically, 16% of women will conceive within the first year of use due to method failure or user failure.
  • Cervical cap plus spermicide
    • In parous women:
      • When used perfectly (consistently and correctly), 26% of women will conceive within the first year of use due to method failure.
      • When used typically, 32% of women will conceive within the first year of use due to method failure or user failure.
    • In nulliparous women:
      • When used perfectly (consistently and correctly), 9% of women will conceive within the first year of use due to method failure.
      • When used typically, 16% of women will conceive within the first year of use due to method failure or user failure.
  • See the section on Comparative efficacy in the CKS topic on Contraception - assessment for an overview of the efficacy of other methods of contraception.

[CoSRH, 2015; WHO, 2022; CoSRH, 2025]

How effective is barrier contraception at preventing sexually transmitted infections?

  • Male condoms
    • Consistent and correct use of male latex condoms is recommended to reduce the risk of transmission of:
      • HIV (non-latex condoms may be recommended to reduce the risk of HIV transmission).
      • Chlamydia trachomatis.
      • Neisseria gonorrhoea.
      • Trichomonas vaginalis.
      • Syphilis.
      • Genital human papillomavirus (HPV).
      • Hepatitis B and C.
      • Herpes simplex virus (HSV) — during symptomatic episodes of HSV, avoidance of sex (vaginal, anal, and oral) may be advisable. Transmission of HSV can still occur by viral shedding even when there are no symptoms.
    • The consistent and correct use of male latex condoms can increase the rate of HPV clearance and regression of cervical intraepithelial neoplasia (CIN).
    • There is insufficient evidence to determine the efficacy of male condoms in preventing the risk of hepatitis A during sexual activity.
  • Female condom
    • Consistent and correct use of the female condom is recommended to reduce the risk of transmission of:
      • C. trachomatis.
      • N. gonorrhoea.
      • T. vaginalis.
      • Genital HPV.
    • Consistent and correct use of female condoms may be advised to help reduce the risk of transmission of:
      • HIV.
      • Syphilis.
      • HSV — during symptomatic episodes of HSV, avoidance of sex (vaginal, anal, and oral) may be advisable. Transmission of HSV can still occur by viral shedding even when there are no symptoms.
    • There is insufficient evidence to determine the efficacy of female condoms in preventing the risk of hepatitis A during sexual activity.
  • Diaphragms and cervical caps
    • There is little evidence that diaphragms and cervical caps reduce the risk of transmission of sexually transmitted infections, including HIV, or the development of CIN.

[CoSRH, 2015]

What are the advantages and disadvantages of barrier methods of contraception?

What are the advantages and disadvantages of male condoms?

  • Advantages 
    • They are easy to obtain and use.
    • They only need to be used during sexual activity.
    • They provide protection against sexually transmitted infections (STIs), including HIV.
    • When used consistently and correctly, male latex condoms can increase the rate of human papillomavirus clearance and regression of cervical intraepithelial neoplasia.
    • They are not compromised by concurrent drug treatment (for example, liver enzyme-inducing drugs).
    • Adverse effects are rare.
    • They are potentially suitable for use by most people as they are a non-hormonal form of contraception.
  • Disadvantages 
    • Forward planning is required, and sex may be interrupted. 
    • The participation and commitment of both partners are required, as well as motivation at each act of intercourse.
    • They are less effective at preventing pregnancy than hormonal and intrauterine contraception.
    • They can break or slip off during intercourse.
    • Loss of sensitivity during intercourse may occur.
    • Men who sometimes lose their erections during sex may find it difficult to use a male condom correctly.
    • Used condoms need careful disposal.  
    • Allergy to latex can rarely occur.

[CoSRH, 2015; Kopa, 2024; WHO, 2025]

What are the advantages and disadvantages of female condoms?

    • Advantages 
      • They are easy to use.
      • They only need to be used during sexual activity.
      • They provide protection against sexually transmitted infections (STIs), including HIV.
      • They can be used with oil-based lubricants because they are made of polyurethane.
      • They can be used if either partner is allergic to latex.
      • They can be inserted at a convenient time (up to 8 hours) before intercourse, so that spontaneity can be maintained.
      • They are less likely to tear than the latex male condom.
      • They are not compromised by concurrent drug treatment (for example liver enzyme-inducing drugs).
      • There are no known adverse effects.
      • They are potentially suitable for use by most women as they are a non-hormonal form of contraception.
    • Disadvantages 
      • They require careful insertion.
      • They require planned use for each act of intercourse.
      • During intercourse, they can slip out, get pushed into the vagina, be dislodged, or the penis can be inserted between the vaginal wall and the condom.
      • They can be noisy during intercourse.
      • The inner ring may cause discomfort during sex.
      • They are less effective at preventing pregnancy than hormonal and intrauterine contraception.
      • Used condoms need careful disposal.  

[CoSRH, 2015; WHO, 2022; WHO, 2025]

What are the advantages and disadvantages of using diaphragms or cervical caps?

    • Advantages 
      • They can be inserted at a convenient time (up to 3 hours) before intercourse so that spontaneity can be maintained.
      • The woman can control the use of contraception.
      • They are not compromised by concurrent drug treatments (for example, liver enzyme-inducing drugs).
      • Adverse effects are rare.
      • They are potentially suitable for use by most women as they are a non-hormonal form of contraception.
    • Disadvantages of diaphragms and cervical caps
      • They are less effective at preventing pregnancy than hormonal and intrauterine contraception.
      • Failure rates for cervical caps (but not diaphragms) may be increased for parous women.
      • They require motivation and careful use on each occasion to be effective.
      • They require planning so that the diaphragm or cap is in place or readily available.
      • The diaphragm or cap must be left in place for at least 6 hours after sexual intercourse.
      • They cannot be used until 6 weeks post-partum or 6 weeks following second trimester termination.
      • The fit needs to be rechecked after weight gain or loss of 3 kg or more, and after giving birth.
      • Some women may be allergic to the material from which the diaphragm is made.
      • They must be used with spermicide, which may cause irritation or allergy.
      • The incidence of urinary tract infection may be increased in some women who use diaphragms — this often relates to the fit and size of the diaphragm, which may put pressure on the urethra.
      • They may not reduce the risk of transmission of sexually transmitted infections (STIs).
      • They should not be used by women at high risk of STIs, as spermicides can increase the risk of infection.
      • They should not be used while menstruating due to an increased risk of toxic shock syndrome.
      • Some women find them messy to use.

[CoSRH, 2015; WHO, 2022; WHO, 2025; Brook, 2026]

Where can people get barrier methods of contraception?

  • Barrier methods of contraception (condoms, diaphragms, and caps) are freely available from:
    • Some general practices and pharmacies.
      • Condoms are not prescribable on the NHS. However, local arrangements allow some GPs and pharmacies to participate in a condom scheme where condoms can be freely given to young people aged 13–35 years.
    • Contraception and sexual health clinics.
    • Young persons' clinics.
    • Brook Advisory Centres (www.brook.org.uk) — for people 25 years of age and younger. 
  • They can also be purchased online or from pharmacies or supermarkets.

Management

Scenario: Male condoms

From age 13 years to 60 years (Male).

How should I assess a person considering a barrier method of contraception?

What information and advice should I give to a person requesting male condoms?

  • Provide verbal and written information on male condoms.
    • This should include information on:
      • How male condoms work.
      • How effective they are at preventing pregnancy, including the failure rate relative to other methods of contraception, such as long-acting reversible contraception (LARC).
      • How effective they are at preventing sexually transmitted infections (STIs).
      • The advantages and disadvantages of the male condom.
      • Where to obtain male condoms.
      • How to use male condoms correctly, including information on when emergency contraception and/or testing for STIs may be required.
    • Information on male condoms is available from several sources, including:

Basis for recommendation

These recommendations are largely based on the College of Sexual and Reproductive Healthcare (CoSRH) clinical guideline Barrier methods for contraception and STI prevention [CoSRH, 2015].

How should a male condom be used?

  • Advise the person that: 
    • Before using the condom, they should check that the packaging has the relevant safety markings (for example, BSI and CE Kitemarks) and that the condom is within the use-by date.
    • A new condom should be used for each episode of sexual intercourse or if applied incorrectly.
    • No more than one condom should be worn simultaneously by one person.
    • Male and female condoms should not be used simultaneously for the same act of intercourse.
    • Care should be taken when handling condoms as sharp objects, such as fingernails, teeth, or jewellery, can tear them.
    • The use of condoms lubricated with spermicide is not recommended. See the section on Spermicide for more information.
    • They should not:
      • Use oil-based products (such as baby oil and petroleum jelly) with latex condoms or with condom brands made from polyisoprene (Skyn®) or lamb intestine (Naturalamb®), as they can damage the latex and make the condom more likely to split. Non-latex male condoms made from polyurethane are unaffected by oil-based lubricants.
      • Apply a lubricant to the penis under a male condom, as this can result in the condom slipping off.
    • Vaginal and topical preparations containing econazole, miconazole, isoconazole, fenticonazole, or clotrimazole may damage latex condoms.
  • Provide information on the correct use of the male condom. 
    • Advise that:
      • The condom should not be unrolled until it is placed on an erect penis.
      • The condom should be rolled down to the base of the penis before there is genital contact.
      • If the condom does not reach the base of the penis, then it is likely that the condom is inside out. It should be removed and replaced with a fresh one.
      • After ejaculation, the man should withdraw before the penis goes soft.
      • Removal of the condom from the penis should occur away from the vagina, anus, or genital area.
      • Used condoms should be disposed of by wrapping in tissue and placing in the bin (not flushed down the toilet).
    • Information on male condoms is available from several sources, including:
  • Advise the person that there may be a risk of pregnancy or sexually transmitted infections (STIs) if the condom breaks, splits, slips, or leaks.
    • They should seek advice from a GP, pharmacist, or sexual health clinic because emergency contraception (EC) and/or STI testing may be indicated.
    • EC may also be indicated in the following situations (this is not an exhaustive list):
      • Failure to use condoms as advised when starting or switching contraception.
      • If enzyme-inducing drugs are being used alongside hormonal contraception and condoms are not used during or for 28 days after.
    • See the CKS topic on Contraception - emergency for more information on when EC is indicated.

Basis for recommendation

These recommendations are based on the College of Sexual and Reproductive Healthcare (CoSRH) clinical guideline Barrier methods for contraception and STI prevention [CoSRH, 2015].

How should I manage suspected allergy or sensitivity to male latex condoms?

  • If either partner develops genital irritation due to suspected latex allergy/sensitivity:
    • Check the type of condom being used and whether it is pre-lubricated with a spermicide.
      • Reactions to spermicides are more common than reactions to latex.
      • The use of condoms lubricated with spermicide is not recommended.
    • Exclude alternative diagnoses, such as atopic eczema, contact dermatitis, or vulvovaginal candidiasis. For more information, see the CKS topics on Eczema - atopic, Dermatitis - contact, and Candida - female genital.
    • Advise the person to use non-latex condoms. Deproteinized male latex condoms may also be considered.
  • If the symptoms do not resolve after these measures, consider further investigations.

Basis for recommendation

These recommendations are based on the College of Sexual and Reproductive Healthcare (CoSRH) clinical guideline Barrier methods for contraception and STI prevention [CoSRH, 2015].

Deproteinized latex condoms
  • The CoSRH recommends that deproteinized latex condoms can be used for people with a latex allergy. However, this recommendation is based on limited evidence (from a small open study with 19 participants) and may contradict manufacturers' advice [CoSRH, 2015].

Scenario: Female condoms

From age 13 years to 60 years (Female).

How should I assess a person considering a barrier method of contraception?

What information and advice should I give to a woman requesting female condoms?

  • Provide verbal and written information on female condoms.
    • This should include information on:
      • How female condoms work.
      • How effective they are at preventing pregnancy, including the failure rate relative to other methods of contraception, such as long-acting reversible contraception (LARC).
      • How effective they are at preventing sexually transmitted infections (STIs).
      • The advantages and disadvantages of the female condom.
      • Where to obtain female condoms.
      • How to use female condoms correctly, including information on when emergency contraception and/or testing for STIs may be required.
    • Information on female condoms is available from several sources, including:

Basis for recommendation

These recommendations are largely based on the College of Sexual and Reproductive Healthcare (CoSRH) clinical guideline Barrier methods for contraception and STI prevention [CoSRH, 2015].

How should a female condom be used?

  • Advise the woman that: 
    • Before using the condom, she should check that the packaging of the condom has the relevant safety markings (for example, BSI and CE Kitemarks) and is within the use-by date.
    • A new condom should be used for each episode of sexual intercourse or if applied incorrectly.
    • No more than one condom should be worn simultaneously by one person.
    • Female and male condoms should not be used simultaneously for the same act of intercourse.
    • Care should be taken when handling condoms as sharp objects, such as fingernails, teeth, or jewellery, can tear them.
    • The use of condoms lubricated with spermicide is not recommended. See the section on Spermicide for more information.
  • Provide information on the correct use of the female condom. 
    • Advise that:
      • The condom should be inserted before the penis comes into contact with the genital area.
      • The penis should be guided into the condom so that it does not enter between the vagina and the condom.
      • It is normal for the condom to move during intercourse, but it will remain effective if the penis stays inside it.
      • After intercourse, the condom should be removed immediately by twisting the outer ring of the condom to keep the semen inside, then pulling the condom gently out of the vagina. 
      • Used condoms should be disposed of by wrapping in tissue and placing in the bin (not flushed down the toilet).
  • Advise the woman that there may be a risk of pregnancy or sexually transmitted infections (STIs) if the condom breaks, splits, slips, or leaks.
    • She should seek advice from a GP, pharmacist, or sexual health clinic because emergency contraception (EC) and/or STI testing may be indicated.
    • EC may also be indicated in the following situations (this is not an exhaustive list):
      • Failure to use condoms as advised when starting or switching contraception.
      • If enzyme-inducing drugs are being used alongside hormonal contraception and condoms are not used during or for 28 days after.
    • See the CKS topic on Contraception - emergency for more information on when EC is indicated.

Basis for recommendation

These recommendations are largely based on the College of Sexual and Reproductive Healthcare (CoSRH) clinical guideline Barrier methods for contraception and STI prevention [CoSRH, 2015].

Scenario: Diaphragms and cervical caps

From age 13 years to 60 years (Female).

How should I assess a person considering a barrier method of contraception?

What information and advice should I give to a woman requesting a diaphragm or cervical cap?

  • Provide verbal and written information on diaphragms and caps.
    • This should include information on:
    • Information on diaphragms and cervical caps is available from several sources, including:
  • Provide information on how to reduce the risk of sexually transmitted infections (STIs).
    • Advise that:
      • Diaphragms or caps may not reduce the risk of transmission of STIs.
      • When used correctly and consistently, male condoms offer one of the most effective methods of protection against STIs, including HIV. Female condoms are effective and safe but are not used as widely as male condoms.

Basis for recommendation

This information is based on the College of Sexual and Reproductive Healthcare (CoSRH) clinical guideline Barrier methods for contraception and STI prevention [CoSRH, 2015].

How should diaphragms or cervical caps be used?

  • Advise the woman that:
    • Diaphragms and caps should initially be fitted by a trained and competent healthcare professional. She should use the diaphragm or cap with another method of contraception (such as condoms) until she has been reassessed to review the fit of the device and her skills in using it.
    • Before inserting the diaphragm or cervical cap, she should check for any holes or deterioration. The diaphragm or cap should be replaced immediately if there are any holes or puckering. Discolouration with use is normal; the latex is unaffected.
    • Diaphragms and caps must be used in conjunction with a spermicide.
    • Oil-based products (such as baby oil, some topical corticosteroids, and oestrogen preparations) are likely to damage latex diaphragms and caps and may render them less effective as a barrier method of contraception.
    • An alternative contraception method should be used during her period.
    • The fit of the diaphragm or cap should be rechecked by a trained healthcare professional:
      • After childbirth, termination of pregnancy, or miscarriage. Women are advised to wait 6 weeks after delivery before using the diaphragm or cervical cap, to allow the uterus to return to its pre-pregnancy size and condition.
      • If she experiences significant weight gain or loss (3 kg or more) as the vagina and cervix can change shape or size.
  • Provide information on the correct use of a diaphragm or cap.
    • Advise that:
      • When using a diaphragm, approximately two 2 cm strips of spermicide should be applied to the upper surface of the diaphragm. Some spermicide can be applied to the leading edge of the rim to ease insertion.
      • When using a cap, the inside of the cap should be filled about a third with spermicide. Spermicide should not be put on the rim of a cervical cap as it may stop it from staying in place.
      • The diaphragm or cervical cap should be inserted up to 3 hours before sexual intercourse and must be left in situ for at least 6 hours after the last episode of sexual intercourse — sperm in the lower reproductive tract are unlikely to survive after 6 hours. 
      • Diaphragms should be removed within 30 hours of insertion, and caps within 48 hours.
      • Additional spermicide should be applied before sex is repeated or if the diaphragm or cervical cap has been in situ for 3 hours or more before sex takes place. The diaphragm or cervical cap should not be removed to reapply spermicide. 
      • After intercourse, the diaphragm or cap should be washed with mild unscented soap, rinsed well, dried carefully, and stored in a cool place. 
    • Information on diaphragms and cervical caps is available from several sources, including:
  • Advise the woman that there may be a risk of pregnancy if the diaphragm or cap is damaged, dislodged, or used incorrectly (for example, wrongly inserted, removed within 6 hours of sexual intercourse, or is left in for longer than 3 hours before sex and no additional spermicide applied).
    • She should seek advice from a GP, pharmacist, or sexual health clinic because emergency contraception (EC) may be indicated. See the CKS topic on Contraception - emergency for more information on when EC is indicated.

Basis for recommendation

These recommendations are largely based on the College of Sexual and Reproductive Healthcare (CoSRH) clinical guideline Barrier methods for contraception and STI prevention [CoSRH, 2015].

  • The NHS and Brook state that diaphragms and caps should not be used while menstruating due to an increased risk of toxic shock syndrome [NHS, 2024; Brook, 2026].

How should I follow up a woman after a diaphragm or cervical cap has been fitted?

  • Reassess the woman after 1–2 weeks to review the fit of the device and the woman's skills in using it.
    • Ask:
      • If she is comfortable while using the method for the duration of its use, including during intercourse.
      • If she is able to tolerate keeping it in overnight if sex occurs in the evening.
      • If there is an intolerance or adverse effect to the spermicide.
    • Ensure that the woman is able to check the position of the diaphragm or cervical cap before and after intercourse, and recognize if it is correctly positioned.
    • Remind the woman that:
      • When inserted correctly, neither partner should be able to feel the diaphragm or cap. If the diaphragm or cap can be felt or is uncomfortable, she should return to reassess fit or consider an alternative diaphragm or cap or another method of contraception.
      • The diaphragm or cap should be replaced immediately if there are any holes or puckering. Discolouration with use is normal; the latex is unaffected.
    • Advise the woman that the fit of the diaphragm or cap should be rechecked by a trained healthcare professional:
      • After childbirth, termination of pregnancy, or miscarriage. Women are advised to wait 6 weeks after delivery before using the diaphragm or cervical cap, to allow the uterus to return to its pre-pregnancy size and condition.
      • If she experiences significant weight gain or loss (3 kg or more) as the vagina and cervix can change shape or size.

Basis for recommendation

Stakeholder engagement

Our policy

The external review process is an essential part of CKS topic development. Consultation with a wide range of stakeholders provides quality assurance of the topic in terms of:

  • Clinical accuracy.
  • Consistency with other providers of clinical knowledge for primary care.
  • Accuracy of implementation of national guidance (in particular NICE guidelines).
  • Usability.

Principles of the consultation process

  • The process is inclusive and any individual may participate.
  • To participate, an individual must declare whether they have any competing interests or not. If they do not declare whether or not they have competing interests, their comments will not be considered.
  • Comments received after the deadline will be considered, but they may not be acted upon before the clinical topic is issued onto the website.
  • Comments are accepted in any format that is convenient to the reviewer, although an electronic format is encouraged.
  • External reviewers are not paid for commenting on the draft topics.
  • Discussion with an individual or an organization about the CKS response to their comments is only undertaken in exceptional circumstances (at the discretion of the Clinical Editor or Editorial Steering Group).
  • All reviewers are thanked and offered a letter acknowledging their contribution for the purposes of appraisal/revalidation.
  • All reviewers are invited to be acknowledged on the website. All reviewers are given the opportunity to feedback about the external review process, enabling improvements to be made where appropriate.

Stakeholders

  • Key stakeholders identified by the CKS team are invited to comment on draft CKS topics. Individuals and organizations can also register an interest to feedback on a specific topic, or topics in a particular clinical area, through the Getting involved section of the Clarity Informatics website.
  • Stakeholders identified from the following groups are invited to review draft topics:
    • Experts in the topic area.
    • Professional organizations and societies (for example, Royal Colleges).
    • Patient organizations, Clarity has established close links with groups such as Age UK and the Alzheimer’s Society specifically for their input into new topic development, review of current topic content and advice on relevant areas of expert knowledge.
    • Guideline development groups where the topic is an implementation of a guideline.
    • The British National Formulary team.
    • The editorial team that develop MeReC Publications.
  • Reviewers are provided with clear instructions about what to review, what comments are particularly helpful, how to submit comments, and declaring interests.

Patient engagement

Clarity Informatics has enlisted the support and involvement of patients and lay persons at all stages in the process of creating the content which include:

  • Topic selection
  • Scoping of topic
  • Selection of clinical scenarios
  • First draft internal review
  • Second draft internal review
  • External review
  • Final draft and pre-publication

Our lay and patient involvement includes membership on the editorial steering group, contacting expert patient groups, organizations and individuals.

Evidence exclusion criteria

Our policy

Scoping a literature search, and reviewing the evidence for CKS is a methodical and systematic process that is carried out by the lead clinical author for each topic. Relevant evidence is gathered in order that the clinical author can make fully informed decisions and recommendations. It is important to note that some evidence may be excluded for a variety of reasons. These reasons may be applied across all CKS topics or may be specific to a given topic.

Studies identified during literature searches are reviewed to identify the most appropriate information to author a CKS topic, ensuring any recommendations are based on the best evidence. We use the principles of the GRADE and PICOT approaches to assess the quality of published research. We use the principles of AGREE II to assess the quality of published guidelines.

Standard exclusions for scoping literature:

  • Animal studies
  • Original research is not written in English

Possible exclusions for reviewed literature:

  • Sample size too small or study underpowered
  • Bias evident or promotional literature
  • Population not relevant
  • Intervention/treatment not relevant
  • Outcomes not relevant
  • Outcomes have no clear evidence of clinical effectiveness
  • Setting not relevant
  • Not relevant to UK
  • Incorrect study type
  • Review article
  • Duplicate reference

Organizational, behavioural and financial barriers

Our policy

The CKS literature searches take into consideration the following concepts, which are discussed at the initial scoping of the topic.

  • Feasibility
    • Studies are selected depending on whether the intervention under investigation is available in the NHS and can be practically and safely undertaken in primary care.
  • Organizational and Financial Impact Analysis
  • Studies are selected and evaluated on whether the intervention under investigations may have an impact on local clinical service provision or national impact on cost for the NHS. The principles of clinical budget impact analysis are adhered to, evaluated and recorded by the author. The following factors are considered when making this assessment and analysis.
    • Eligible population
    • Current interventions
    • Likely uptake of new intervention or recommendation
    • Cost of the current or new intervention mix
    • Impact on other costs
    • Condition-related costs
    • In-direct costs and service impacts
    • Time dependencies
  • Cost-effectiveness or cost-benefit analysis studies are identified where available. 

We also evaluate and include evidence from NICE accredited sources which provide economic evaluations of recommendations, such as NICE guidelines. When a recommended action may not be possible because of resource constraints, this is explicitly indicated to healthcare professionals by the wording of the CKS recommendation.

Declarations of interest

Our policy

Clarity Informatics requests that all those involved in the writing and reviewing of topics, and those involved in the external review process to declare any competing interests. Signed copies are securely held by Clarity Informatics and are available on request with the permission of the individual. A copy of the declaration of interest form which participants are asked to complete annually is also available on request. A brief outline of the declarations of interest policy is described here and full details of the policy is available on the Clarity Informatics website. Declarations of interests of the authors are not routinely published, however competing interests of all those involved in the topic update or development are listed below. Competing interests include:

  • Personal financial interests
  • Personal family interest
  • Personal non-financial interest
  • Non-personal financial gain or benefit

Although particular attention is given to interests that could result in financial gains or losses for the individual, competing interests may also arise from academic competition or for political, personal, religious, and reputational reasons. An individual is not obliged to seek out knowledge of work done for, or on behalf of, the healthcare industry within the departments for which they are responsible if they would not normally expect to be informed.

Who should declare competing interests?

Any individual (or organization) involved in developing, reviewing, or commenting on clinical content, particularly the recommendations should declare competing interests. This includes the authoring team members, expert advisers, external reviewers of draft topics, individuals providing feedback on published topics, and Editorial Steering Group members. Declarations of interest are completed annually for authoring team and editorial steering group members, and are completed at the start of the topic update and development process for external stakeholders.

Competing interests declared for this topic:

None.
